Abstract: The reform of the administrative examination and approval system implemented by local governments is an important breakthrough for the transformation of government functions and the simplification and decentralization of government in recent years. This paper, based on the innovation index data which distinguish the difference of patent value between different ages and the date of establishment of the city administrative examination and approval center collected by hand, applies the multi-period difference-in-difference model to conduct an empirical study of the impact of the administrative examination and approval system reform on China's urban innovation. The results of the study are as follows: Firstly, the reform of the administrative examination and approval system has a significant positive effect on promoting the level of urban innovation in general, and the positive effect increases with time. Secondly, the innovative environment of the city itself has a strong restrictive effect on the innovation effect of the administrative examination and approval system reform. Thirdly, further research finds that the level of the urban economic development, financial development, openness to the outside world and the level of the human capital are the key elements of the urban innovation environment in China, and play a significant positive regulatory role in the innovation effect of the administrative examination and approval system reform. The research of this paper has certain enlightenment significance for local governments to promote high-quality economic development through institutional innovation.
